🗑
mA X Seconds = mAs   show
🗑
radiation intensity is inversely proportional to the square of the distance I1 / I2 = SID2 squared / SID1 squared   show
🗑
to maintain a constant radiographic intensity (density), the mAs must be directly proportional to the square of the distance mAs1 / mAs2 = SID1 squared / SID2 squared   show
🗑
Below 85 kVp, an adjustment of 2 kVp/cm will compensate for small changes. Above 85 kVp, a change of 3 kVp/cm is necessary   show
🗑
For a 2 cm increase in patient size, increase the mAs by 30% (multiply by 1.3) per 2 cm. For a 2 cm decrease in patient/part size, decrease the mAs by 20% (multiply by 0.8) per 2 cm   show
🗑
to increase contrast (more difference between shades) decrease the kVp by 15% and multiply the mAs by 2. To decrease contrast, increase latitude and lower patient dose, increase kVp by 15% and divide the mAs by 2   show
🗑
show Relative speed formula  
🗑
show Grid conversion formula  
🗑
